That should be right, because the absolute value of -9 would be 9, but the negative sign in front makes it -9.

Your selected answer is correct because the absolute value of -9 is 9, and the negative sign outside the absolute number symbols makes it 9 negative, so -9=-9. BUT, we notice that there are choices for "greater than or equal to" and "less than or equal to". Those ones are correct too because it can be one or the other (greater than or equal to, less than or equal to).

Equal to, less than or equal to, greater than or equal to (Choices 3, 4, and 5)

3. x + 4y = 30 x - 2y = 0

kolbaska11 [484]

Answer:

Step-by-step explanation:

Given that:

x + 4y = 30

x - 2y = 0

Subtracting both equations:

6y = 30

y = 30/6

y = 5

Putting in above equation

x + 4(5) = 30

x + 20 = 30

x = 10

Find the 70th term of the following arithmetic sequence. 12,17,22,27,...

nikdorinn [45]

Since it starts at 12 and is increasing by 5 each time, the 70th term will be;
12 + 5(70)
12 + 350
362

362 is the 70th term of the sequence.

annual sales for a company are $149,999 and are increasing at a rate of 6% per year. write an exponential growth function to mod

elixir [45]

Answer:

S(t) = 149999(1.06)^t
$225543

Step-by-step explanation:

Initial value is $149999
Increase rate is 6% per year = 1.06 times

The model of the growth is:

S(t) = 149999(1.06)^t, where S- amount of annual sales, t- time in years, 1.06- growth rate per year

Annual sales after 7 years:

S(7) = 149999(1.06)^7 = $225543

Use substitution. What is the solution to the system of equations? Use the drop-down menus to explain your answer.

X would be 0 and y would be 2 so it would be (0,2)

I GIVE BRAINLIEST FOR EXPLANATION AND CORRECT ANSWER EXTRA POINTS 3

sveticcg [70]

Answer:

$x=8$

Step-by-step explanation:

The best way to go about this is to use a trig identity. You have the unknown opposite the angle and the hypotenuse, so its best to use the sine identity: $sin(x)=\frac{O}{H}$ , where O is the opposite side, and H is the hypotenuse.

Set up the equation as: $sin(27)=\frac{x}{17}$ , and solve for X.

I got x=7.718, rounded to x=8.

If I helped, a brainliest answer would be greatly appreciated!
